Answer:

1555 people

Step-by-step explanation:

First, average the votes for polar bears.

(46 + 43 + 49)/3 = 46

Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.

x/3380 = 46/100

x = 1554.8

Round to the nearest whole number to get 1555.

Two choises! Pick the right one!
slava [35]

Answer:

The function has a maximum value of 3 that occurs at x = 1.

Step-by-step explanation:

First, note that the leading coefficient is negative. This means that the parabola will curve downwards. Because of this, the function has a maximum. The maximum value will simply be the vertex.

The formula for the x-coordinate of the vertex is -b/2a.

a=-3, b=6, c=0

Plug in the numbers:

x=-(6)/2(-3)

=-6/-6=1

Now, plug 1 back into the original function:

-3x^2+6x

-3(1)^2+6(1)

=-3(1)+6

=-3+6

=3

<h2>Answer:38.33 Kg</h2>

Step-by-step explanation:

If mKg of mass is placed on spring with spring constant k,

mg=kx

where g is universal gravitational constant

x is the displacement in the spring.

In case 1:

25g=k(0.15)\\k=\frac{25g}{0.15}

In case 2:

mg=k(0.23)

Using  result from case 1,

mg=\frac{25g}{0.15}\times 0.23

m=38.33Kg

A coffee shop spends $408 for an order of 17 cases of paper cups.
solong [7]

Answer:

Option C is correct

$528 will the total cost spends by coffee shop

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates.

As per the statement:

A coffee shop spends $408 for an order of 17 cases of paper cups.

Unit rate per cases = \frac{408}{17} =\$24

Now, if If the coffee shop adds 5 more cases of paper cups to the order

then,

total number of cases = 17 +5 = 22 cases

To find how much  total cost coffee shop spends.

Total cost = unit rate \times total number of cases

                 = 24 \times 22 = \$528

Therefore, total costs coffee shop spends = $528
